What Causes a Tingling Tongue?

10. Vitamin B Deficiencies

Low levels of vitamins B12 and B9 (folate) sometimes lead to tongue sores and impact how food tastes. A tingling sensation in the tongue, feet, and hands is one possible symptom. People with vitamin B deficiencies often feel tired. The condition can progress to anemia if not addressed. The deficiencies occur when the body cannot absorb the necessary vitamins from food. Age is one factor since our stomachs become less acidic over time. A doctor may prescribe medication or counsel deficient patients to eat more fish, eggs, meat, and dairy, which are rich in vitamin B12. Vegans can eat or drink fortified soy or nut milk, bread, cereals, or grains, or take supplements. Good sources of B9 are green, leafy vegetables, peanuts, beans, orange, and tomato juice.
